Overview

• Kalshi reports September trading at $1.3 billion so far and a 62% global market share, up from roughly 3% a year ago, according to company data cited in new coverage.
• Growth is tied to a pivot into NFL-focused markets, with newly registered prop-style contracts, parlays launched on September 5, and promotions linked to NFL on Fox.
• The platform logged a single-day record of 588,520 trades during NFL Game Week 2, reflecting heightened interest in sports event contracts.
• Massachusetts filed a 43-page lawsuit seeking to permanently bar Kalshi, calling its sports products illegal wagering and flagging its 18+ policy versus the state’s 21+ online betting rule and lack of a state license.
• Regulators in Maryland, Nevada, and New Jersey have issued cease-and-desist orders now in federal court, and Kalshi counters that it operates lawfully as a CFTC-regulated designated contract market with federal preemption.
